The Baseband Software System Design Of UHF RFID Reader Accord With The ISO18000-6C Standard

With the rise and development of related technologies of the Internet ofThings(IOT), RFID products has been widely used in transportation, power grids,logistics and other areas. Market demand for related products is also increasing. In thecountry, RFID product categories are few and the price is high. In view of this situation,this paper designed a low-cost RFID reader which based on ISO18000-6C protocol,radio frequency identification range around915MHz. The main work of thispaper is developing the software system from the purpose of independentinnovation.In the first place, this paper briefly describes the principle of RFIDtechnology, analyzes the current development of radio frequency identification athome and abroad in recent years, highlights the reader‘s application prospect inthe life and research background of this topic.In the second place, describes the composition of the UHF RFID system, keytechnologies of RFID system, and RFID standards. Data transmissiontechnology of RFID system is briefly introduced emphasized the basebandcoding and data encryption. ISO18000-6C protocol is compared withISO18000-6B protocol, emphasizing the superiority of ISO18000-6C protocol,and then leads to the framework of the software system design.Again, a brief analysis of software requirements and software developmentplatform selection are introduced. Describes the modules of the software system,application interface module is analyzed in detail. Then the idea of softwaresystem is designed, depending on the properties of the reader software. At lastdecided to design the entire system based on the event-driven model, and thendetermine the methods and processes of software development.Finally, analyze the ISO18000-6C protocol, designed the software system inaccordance with provisions of the agreement and the requirements of this project.Describeing the specific design and implementation process of the uplink anddownlink of the physical layer, each commands and tag operation of tagidentification layer. The detailed design process and problems during the design are summarized in this paper. The software system was tested in the final stage ofthe project. Insufficient of this project were put forward and the outlook on futurewas made.
